| | Furthermore, the SGSN then stores the relation between the MCAddr and the MS-HostID by for example simply adding the Multicast Address to the existing PDP-context information for that user to be able to replicate the data and forward these to the corresponding hosts at reception of the multicast data stream. | | | Based on this information the SGSN may decide to de-register from the TLMG, since it requires more processing capacity from the SGSN to discard multicast traffic than is gained from the multiplexing. | | | [0054] In a mobile environment like in UMTS the idea could be implemented by using IP multicast for efficient transmission in the IP network between the SGSN, which is an example of a serving node and the GGSN, which is an example of a router. |

| | This information is preferably a binary field, one state of which shows that the SGSN has changed, and the other state of which shows that the SGSN has not changed. | | | Furthermore, even though the contexts were already created in the new SGSN, state variables at the ends of the logical link do not match and data transmission fails, at least temporarily. | | | [0067] In the routing area update procedure between two SGSNs (inter-SGSN) the serving SGSN changes and, according to the invention, the MS should be informed of the change so that the MS can initiate a local procedure or a network procedure for updating a logical link. |

| | At PDP context activation, the SGSN performs a DNS query to find out the GGSN(s) serving the APN requested by the terminal. | | | Effectively, this would mean that each APN in a GGSN would have a certain number of /64 prefixes that can be handed out at PDP context Activation, through Router Advertisements. | | | Note that the recommended solution does not imply or assume that the mobile device is a router. |
